A High-Speed Television System for Motion Analysis
A high-speed television camera and recorder system records images up to 2000 full frames/sec, or 12,000 partial frames/sec. The system employs a unique parallel recording format and solid state image sensor to record information at a maximum rate of 100 million pixels/sec. The data is recorded using a high-density head-tape combination which achieves an equivalent recording density of 5 million bits/in2 of tape, providing the required recording bandwidth of 265 MHz at a tape velocity of 200-in./sec. The system was designed for motion analysis applications, and includes a digital frame store for time-base correction and still-frame/slow-motion replay. Single frames may be accessed and held on command, stepping forward or backward. Internal microprocessors control and monitor the cassette-loaded recorder, the signal processing system, and the operator interface, while providing built-in measurement and analysis tools. In addition, the system may be operated under the control of a computer system to synchronize operation with a larger system and perform image enhancement and pattern recognition functions.
